When attacks from the Mirai botnet hit the network in 2016, we all knew something was different. You could feel it. In a 31-day span, the internet suffered three record-breaking attacks; Brian Krebs’ at 620 Gbps, OVH at 1.2 Tbps, and the widespread outages caused by the attack on Dyn DNS. Also within that window, […]

Newton’s geopolitical version of the law can only lead to escalation as two opponents go back and forth, iterating through several responses.
In June 2021, I wrote a blog questioning if decade-old denial-of-service tools were still relevant.
